media:
Specific hazards arising Explosion risk in case of fire. Fight fire remotely due to the risk of explosion.
Take care as it may decompose upon combustion or in high temperatures to
from the chemical:
generate poisonous fume.
Precautions for firefighters: Fire-extinguishing work is done from the windward and the suitable fire-extinguishing
method according to the surrounding situation is used. Uninvolved persons should
evacuate to a safe place. In case of fire in the surroundings: Keep containers cool by
spraying with water. Eliminate all ignition sources if safe to do so.
Special protectiveWhen extinguishing fire, be sure to wear personal protective equipment.

Section6. ACCIDENTAL RELEASE MEASURES
Personal precautions,Use extra personal protective equipment (P3 filter respirator for toxic particles). Keep
protective equipment and people away from and upwind of spill/leak. Entry to non-involved personnel should
emergency procedures: be controlled around the leakage area by roping off, etc.
Environmental precautions: Prevent product from entering drains.
Methods and materials for Sweep dust to collect it into an airtight container, taking care not to disperse it.
containment and cleaning Adhered or collected material should be promptly disposed of, in accordance with
up: appropriate laws and regulations.
Prevention of secondary Remove all sources of ignition. Fire-extinguishing devices should be prepared in

Section7. HANDLING AND STORAGE
Technical measures:Handling is performed in a well ventilated place. Wear suitable protective equipment.
Be careful not to cause leakage, overflow, or dispersion. Steam should not be
generated unnecessarily. Keep away from heat/sparks/open flame/hot surfaces. -No
smoking. Take measures to prevent the build up of electrostatic charge. Use
explosion-proof equipment. Avoid shock and friction. Wash hands and face before
breaks and immediately after handling the product.
Use a closed system if possible. Use a local exhaust if dust or aerosol will be
generated.
Advice on safe handling: Avoid contact with skin, eyes and clothing.
Conditions for safe storage, including any
incompatibilities
Storage conditions:Keep container tightly closed. Store in an explosion-poof freezer.
Store under inert gas.
Protect from moisture.
Store locked up.
Be sure not to give the container unexpected impacts, such as falling down or falling
off.
Store away from incompatible materials such as oxidizing agents.
Heat-sensitive, Moisture-sensitive, Air-sensitive
Packaging material:Comply with laws.

Section8. EXPOSURE CONTROLS / PERSONAL PROTECTION
Engineering controls:Install a closed system or local exhaust. Also install safety shower and eye bath.
Personal protective equipment
Respiratory protection: Dust respirator, self-contained breathing apparatus(SCBA), supplied air respirator,
etc. Use respirators approved under appropriate government standards and follow
local and national regulations.
Hand protection:Impervious gloves.
Eye protection:Safety goggles. A face-shield, if the situation requires.
Skin and body protection: Impervious protective clothing. Protective boots, if the situation requires.
